Create a .bash_profilein your home directory. Then, add the line
.bash_profile在您的主目录中创建一个。然后，添加行
PYTHONPATH=$PYTHONPATH:new_dir
EXPORT $PYTHONPATH
Or even better:
或者甚至更好：
if [ -d "new_dir" ] ; then
PYTHONPATH="$PYTHONPATH:new_dir"
fi
EXPORT $PYTHONPATH
The .bash_profileproperties are loaded every time you log in.
该.bash_profile特性被加载每次登录的时间。
The sourcecommand is useful if you don't want to log in again.
source如果您不想再次登录，该命令很有用。
